Observe normal precautions appropriate to the circumstances and quantity of material handled. Cyclodextrins are fine organic powders and should be handled in a well-ventilated environment. Efforts should be made to limit the generation of dust, which can be explosive. 

Oxidisable organic materials of high surface to volume ratio (carbon powder, foamed elastomers, lampblack, sawdust) react very violently, even at -78°C, with perchloryl fluoride, which should be handled with the same precautions as liquid oxygen.

Prepn is by passing H2 over coarsely ground U at 250° the yield is quant. The hydride ignites spontaneously in air, and must be stored and handled under N2 or C02. It reacts very violently with w, and explosively with organic halides. The hydride is also violently attacked by halogens to form U halides...
